LB7: Truck feels fast for a short time......

[JustinD]

I have been having issues with my truck for a while now, did a new LB7 CP3 and LBZ regulator along with my new II turbo, then we found 3 injectors be to be bad, replaced those, truck felt great for about 3 hours, then started to feel sluggish, dynoed it 2 days after I got it back, made 523 which I understand is about normal for my setup, but it feels sluggish now?? I changed tunes and it felt great again but same thing it was short lived. I am going to try to reset TAPS later tonight and see if that works??? Any ideas?? Any help would be greatly appreciated, I am very close to just getting rid of it and buying a 1500 with a 5.3 no issues!!!

I keep checking my balance rates, they seem ok too.

 

[jmaz268]

Have you logged rail pressure?

 

[JustinD]

Here is one with balance rates, and the other was when it actually felt good. I'll have to log it today while it feels like a turd.

 

[Evan@InglewoodTrans]

Does the truck feel sluggish in every gear or does it feel good then fall on its face?

 

[Evan@InglewoodTrans]

Also have you sent your tuner that second log?

so that 523 you made, what that a peak and then a slop off after that or did it look consistant across the page? this is not a dig, its only to see if power is dropping out and what we can do to fix it :hug:

 

[JustinD]

Feels ok up top like highway speeds. I have sent Jeff the logs too but he is traveling for the next few days, just wanted to see if it was an obvious problem?

tq reading was a little screw because his pick up was screwed up.

 

[JustinD]

Thanks for all the help guys I hope it can be figured out. :hug:

that actually looks reaaaaaally good justin! have you done any transmission logs? is the TC locking up everytime when its suppose to?

 

[JustinD]

I haven't logged TCM yet, I will.

 

[JustinD]

I don't see a PID seection for the TCM parameters?

 

[JustinD]

Found them, just not sure which I should be looking at? Anyone have a PID selection they could share for the TCM?

 

[JustinD]

Just reset TAPS it flares hard now when it shifts, will it adapt and be smoother?? I am willing to drop this truck off and let someone just fix it, anyone interested???

Justin email me a log and ill see what it looks like , I can also send over a pre configured PID list for lock up if it looks like thats the problem . [email protected]

 

[JustinD]

Cool thank you Trent!!

My log shows only 20.0* when the highlighted cell @ 110 mm3 3000-3400 should be 24.8-32.8?
